Our Abpromise guarantee covers the use of ab3317 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
IHC-P Use a concentration of 5 µg/ml. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.
ICC/IF 1/1000. PubMed: 18986984
WB 1/1000. Detects a band of approximately 56 kDa (predicted molecular weight: 49 kDa).

This antibody detects a 56 kDa protein representing proteasome 19S subunit S4 in HeLa cell lysate. This antibody detects, to a lesser extent, an ~35 kDa protein which could correspond to subunit degradation product.

IP Use at an assay dependent concentration.


  • Function

    The 26S protease is involved in the ATP-dependent degradation of ubiquitinated proteins. The regulatory (or ATPase) complex confers ATP dependency and substrate specificity to the 26S complex.
  • Sequence similarities

    Belongs to the AAA ATPase family.
  • Cellular localization

    Cytoplasm. Nucleus.

  • Western blot of proteasome 19S subunit S4 on HeLa cell lysate using ab3317.

  • ab3317 staining Proteasome 19S S4/PSMC1 in mock transfected rat primary neurons by Immunocytochemistry/ Immunofluorescence. Primary cultures of rat hippocampal neurons were prepared from E18 rats. Cells were fixed in 4% paraformaldehyde and incubated with primary antibody at 1/1000 dilution. The image show red staining with ab3317, nucleus was stained blue with Hoechst H33258 and right image show merged images. The green color seen in image is the GFP staining in similar experiment.

  • IHC image of ab3317 staining in human skin formalin fixed paraffin embedded tissue section, performed on a Leica BondTM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab3317, 5µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

    For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

Thank you for your enquiry. I have been in touch with the source of this antibody and the originator has confirmed that this antibody was in fact raised using full length yeast proteasome 19S subunit S4 and was not a tagged version of the protein. I hope this information helps, please do not hesitate to contact us if you need any more advice or information.
